Questions about this item

How does the 12 V 0.75 A rating translate to cooling performance in a Lenovo B540P?

The 12 V 0.75 A rating sets the fan's maximum power draw at 9 watts, giving the B540P's GPU and CPU cooler enough headroom to spin up under heavy load without exceeding the motherboard's fan header limit.

What does the DC 12 V interface cap in practice for this KUC1012D BK43 replacement fan?

The DC 12 V interface caps the fan at 12 volts, so speed is controlled by varying voltage within that ceiling; it cannot draw more than 0.75 A, limiting peak airflow to what 9 watts can deliver.
